"Lately it seems like me just standing up is risking my life,” Michaels joked to Trump, who asked if Michaels was putting his health in jeopardy by appearing at the New York finale.

Just a month prior to the finale, Michaels was rushed to the hospital after suffering a brain hemorrhage. He was listed in critical condition for 10 days, then released to out-patient rehabilitation. Though his rate of recovery was considered rare, Michaels was back on his way to "Apprentice."

Then he suffered a small stroke.

In a statement posted last week on his website, Michaels said he was diagnosed with patent foramen ovale, or a hole in the heart, after experiencing numbness on the left side of his body.

So Sunday came as a victory for the resilient singer, who defeated Robinson Peete in a challenge to create and market a celebrity drink for Snapple. Peete's HollyRod Foundation, however, scored its own $250,000 from the iced tea makers.

The singer was in good spirits but appeared to walk with a limp and exhibited some slack in the left side of his face, a report said.
